Connect USB Devices
You can use locally aached USB devices, such as thumb ash drives, cameras, and printers, from a remote
desktop. This feature is called USB redirection.
When you use this feature, most USB devices that are aached to the local client system become available
from a menu in Horizon Client. You use the menu to connect and disconnect the devices.
N With View Agent 6.1 or later, or Horizon Agent 7.0 or later, you can also redirect locally connected
USB thumb ash drives and hard disks for use in RDS desktops and applications. Other types of USB
devices, including other types of storage devices, such as security storage drives and USB CD-ROM, are not
supported in RDS desktops and applications.
Using USB devices with remote desktops has the following limitations:
n
When you access a USB device from a menu in Horizon Client and use the device in a remote desktop,
you cannot access the device on the local computer.
n
USB devices that do not appear in the menu, but are available in a remote desktop, include human
interface devices such as keyboards and pointing devices. The remote desktop and the local computer
use these devices at the same time. Interaction with these devices can sometimes be slow because of
network latency.
n
Large USB disk drives can take several minutes to appear in the desktop.
n
Some USB devices require specic drivers. If a required driver is not already installed on a remote
desktop, you might be prompted to install it when you connect the USB device to the remote desktop.
n
If you plan to aach USB devices that use MTP drivers, such as Android-based Samsung smart phones
and tablets, congure Horizon Client so that it automatically connects USB devices to your remote
desktop. Otherwise, if you try to manually redirect the USB device by using a menu item, the device is
not redirected unless you unplug the device and then plug it in again.
n
Do not connect to scanners by using the Connect USB Device menu. To use a scanner device, use the
scanner redirection feature. This feature is available for Horizon Client when used with View Agent
6.0.2 or later or Horizon Agent 7.0 or later. See “Using Scanners,” on page 92.
n
Webcams are not supported for USB redirection using the Connect USB Device menu. To use a
webcam or audio input device, you must use the Real-Time Audio-Video feature. This feature is
available when used with View 5.2 Feature Pack 2 or a later release. See “Using the Real-Time Audio-
Video Feature for Webcams and Microphones,” on page 86.
n
The redirection of USB audio devices depends on the state of the network and is not reliable. Some
devices require a high data throughput even when they are idle. If you have the Real-Time Audio-
Video feature, included with View 5.2 Feature Pack 2 or a later release, audio input and output devices
work well using that feature, and you do not need to use USB redirection for those devices.
